The grass in question was fine last Fall, no issues. The patch of grass in question, is roughly 16x10, and appears spongy in some places when walking on.

Years ago. I took a section of my lawn to the UNH Extension school in Durham.
I was directed to one office/professor.
And he imediately promptly answered my question.
Had no appointment. Just walked in.
